Juventus be warned, Real Madrid's attack is so potent it is making opponents cry.

Cristiano Ronaldo has scored 20 goals in 15 matches, and the Portugal forward needs only one more in the next three games to match the group stage record of eight in a season, held by Ruud van Nistelrooy, Filippo Inzaghi and Hernan Crespo.

Ronaldo has had help from teammates Karim Benzema and Gareth Bale, who turned provider for three of his last five goals.

The Wales winger has scored two goals himself this week. Rayo Vallecano defender Anaitz Arbilla was in tears moments after Bale easily beat with him with a playful touch en route to a goal on Saturday.

A Madrid victory ensures advancement to the knockout stage, while a draw will also be enough if Galatasaray does not lose at Copenhagen.

TIME FOR TEVEZ

Carlos Tevez has started well for Juventus with six league goals this season, but goals have been a lot tougher to come by in the Champions League.

Tevez's last goal in Europe's premier competition came in April 2009, when he played for Manchester United.

"Has it really been that long since my last Champions League goal?" Tevez asked journalists when presented with the fact on Monday. "If I haven't scored for four years, then let's hope that changes tomorrow."

Juventus certainly needs the Argentine to find the net as a defeat could all but end its chances of qualifying for the next stage. Juventus has just two points from three games after losing 2-1 at Madrid.

"We've got to win all three (games remaining)," Tevez said. "This game is like a final and we've got to play it like that."

Madrid's visit is just the start of a testing week for Juventus, with an important Serie A match against Napoli, which is joint-second alongside it three points behind leader AS Roma, looming.

GET REAL

Madrid coach Carlo Ancelotti has warned his players to drop their egos and get back to basics after a "disastrous" defensive performance in a 3-2 win at Rayo.

Madrid's defense seemed to implode after Pepe caused a penalty, with an undisciplined tackle from Marcelo two minutes after that allowing Rayo to claw back into the game.

Ancelotti has already warned his players of the need to change their attitudes with the next round beckoning.

"We're attacking very well, but we're allowing too many goals," Ancelotti said. "It's an important game for Juventus but for us it's an opportunity to qualify for the next stage. The sooner we do that, better for us."

Goalkeeper Diego Lopez should give way to Iker Casillas despite an extraordinary performance at Rayo, while Raphael Varane returns to the center of defense to replace either Pepe or Sergio Ramos. Midfielder Xabi Alonso is also expected to play in the Champions League for the first time this season.

HOME FEELING

Juventus is counting on its local support and impressive home record against Madrid.

The new Juventus Stadium has proved somewhat of a fortress in the Champions League with Bayern Munich the only team to emerge victorious in Turin. In its old stadium, Juventus had lost only twice in the competition in 10 years.

"We need to make our home advantage count because, apart from determination and the right tactics, the atmosphere will be important," Conte said. "I'm expecting our fans to provide a red-hot atmosphere, not only when the game is going our way but also when the game isn't going our way. They need to push the players to overcome a hurdle, a very high one at that."

Madrid hasn't won at Juventus since 1961-62. Since then, Juventus has racked up five straight wins over its Spanish rival.

The last time either team won away was 1986 when the Italians won at the Bernabeu.

GALATASARAY INJURIES

Galatasaray can take a big step toward reaching the knockout stage, but it will have to do it without two key players.

Goalkeeper Fernando Muslera is likely to sit out the trip to Copenhagen with a broken toe, leaving backup Eray Iscan to make his first appearance since undergoing knee surgery in September.

Wesley Sneijder's nagging right thigh could also keep the Netherlands midfielder from taking part.

The Turkish club can take a big step toward advancement with a victory, but Copenhagen is unbeaten at home in the group stage over the past eight seasons, including a 1-1 draw against Juventus this season.
